I make a point of walking to the Cherry Hinton Tesco to get my lunch most working days rather than using the sandwich shop inside the main ARM building; that's about a 20-minute round trip (not counting the faffing at checkouts). I visit the Gallery most Sundays, which is a 15-minute walk there and another one back. I try to walk into town when I go shopping at weekends, which might come to an hour of total walking time, but that doesn't happen most weeks for one reason or another. So I might guess at an average of perhaps twenty minutes of walking a day, or perhaps slightly less. Any journeys longer than that I tend to drive for.

When I was living at the Gallery and working in Bateman Street I used to walk 45 minutes to work and 45 minutes back again every weekday; now that gets you pretty fit without needing much extra deliberate exercise. It's been years since I did that, though...

Hmm, that's the kind of total amount of walking that I do per week as well. Although not at the moment cos I'm cycling it!
